State of Rhode tain new and useful Iiiprovementain Short Circuitin'g Mechanism, of Vwhich the follow.

in is a specification.

his invention 'relates to a key-operated mechanism for short circuiting anelectric ect of this invention is torovide a simp'e; inexpensive and effective'means whereby the electric current in an internal combustion engine may to render the 'ne inoperative.

ith these and other objects in view, the o-certain novel features of construction, vas will be more Vfully described, and particularly pointed ont in the apfended claims.

In tie accompanying drawings:

Figure 1'- is a sectional side elevation of my improved short-circpiting mechanism. Fig. 2 's a front view Vof the device partly broken away to illustrate the connec-v tion of the binding post with the conductor member. Fig. 3- s a sectional .view looking from the rear of the device, showing the4 'sliding contact plate which is moved by the key to com lete the short circuiting path.

Fig. 4- is a sectional side elevation showing my improved device in operating position n the vehicle.

`Re rring tothe drawings, 10 indicates the engine of a. motor vehicle and 11 the transmission housing within which is set the ma eto or electric current generator of whic the member 12 is fixed while the member 13 is rotated through the action of the fly wheel 14, all of which is mounted beneath the foot board-15 or body portion of the vehicle.

My improved short-circuiting device nia be constructed in any suitable way, but preferably construct the same with a hollow or tubular standard or `casing 16 which is preferably formed of conducting material sncli ns cast brass, iron, or the lke, the head 17 of which is enlarged and boredat 18 for the reception of the lockA orkey actuated mechanism 19.

Nithin this tubular standard I have nmunted a rod .20 of conducting material v Specification ot Letten Patent. application martin-nary 1s, isis. semi no. 211,713.

which is insulated from the standard proper by .a surrounding core 21. This insulating core performs three functions; first, it'insulates the rod from the standard; second, it

' su ports the rod centra-lly4with thestand- 60 a and third, it stdens the standard so that its thin, tubul r walls can withstand.v l. a ter shock wishoiitbecominggbrken: i t 22 this conductor meinberlin slightly-,1 enlar ed and into the 'enlarged goxtontistt thre ed a binding post 23j# Y hic exteiids- ,ls ating co r threaded at its outer end for the nut. with which tosecure the circuit wire25- which extends u to the ignition coil 38. 0n the ower end of this conductor rod 20 is a coil spring 26 which serves as a yieldable electrical connection between this conductor and the contact pin 27, which pin is de fixed plate 2 8 of the 7 6. eto or generatoin ,f he upper end of this conductor rod 20 is also provided with yanother yielding'pin 29 mounted in a recess therein and is resse outwardly by m'ans of the'spring 50 also 80 mounted in the recess in the rod. .The upfY per eige 31 of this recessed rtioiiis turned mwa ly forming a shoul er to limit the outward motionV of this-contact pin 29. The key actuated locking mechanism is 86 provided with a sliding ate 40 which is arranged to move verticallly'in the groove 32 and isA provided with a rearwardly extending operating pin 33. The rotating member 34 of the lock 1s provided with an operatin in 35 whereby when this member is rotates in one direction the pin 34 contacts with in 33 and moves this plate downwardlyr so t at its end 36v engages the yielding 'in 29 to complete the short circuiting pat hack to the engine casing, through this plate, the rest of the key-actuated mechanism, through the standard 16 and the attaching screws or bolts 37.

In order to open this short-circuiting path and restore the effectiveness of the normal; circuit, it is only necessary to turn the key in the opposite direction, which will causar be moved around beneath the pin 33 and so raise the sliding plate l out 10 of contact with the yielding contact pin 29. In some makes of motor `vehicles the yieldf ing Contact pin 27 is mounted ima suitable support (not shown) and formsg. part of the standard equipment to which`i`s con- Illa nected a conductor wire .leading up to the this support and inountthis contact pin at.
